What You Should Know About P0056 Code for Chevy Silverado

AvatarByCarl Frisch

The P0056 code is a diagnostic trouble code (DTC) for an oxygen sensor heater circuit malfunction in a Chevy Silverado. This code is triggered when the powertrain control module (PCM) detects an abnormal voltage or resistance in the oxygen sensor heater circuit, indicating that the heater is not working correctly. The most common causes of this code are a defective oxygen sensor, faulty wiring, or a bad PCM. In order to diagnose and repair this issue, the technician will need to use a diagnostic scan tool to retrieve any stored codes and monitor the data stream. Then they will need to visually inspect all related wiring and components for damage or wear. If no visible issues are found, then they may need to replace the oxygen sensor or PCM depending on their findings.

Diagnosing P0056 Code in Chevy Silverado

Diagnosing a P0056 code in a Chevy Silverado can be tricky. The code is related to the oxygen (O2) sensor bank 2 sensor 2, which is located in the exhaust system. Symptoms of this code may include: a decrease in fuel economy, poor engine performance, illuminated check engine light, and hesitation or stalling.

Causes of this code can be attributed to a faulty O2 sensor, corroded wiring and connectors, or faulty fuel injectors. To diagnose this code correctly it is important to perform a few key diagnostic tests.

The first step in diagnosing a P0056 code should be to visually inspect all the wiring and connectors associated with the O2 sensor Bank 2 Sensor 2. If any corrosion is found then it should be cleaned and repaired as needed. Next, if no visible damage is found then it’s time to test the O2 sensor itself using an appropriate OBD scanner or digital multimeter. If readings are out of range then it’s likely that the O2 sensor needs replacing. Lastly, if all readings are within normal range then it’s recommended that you check for any other fault codes stored in the vehicle’s computer system as there may be other underlying issues that need addressing.
